In this study, engine performance on thermal factors for different biodiesels has been studied and compared with diesel fuel. Biodiesels were produced from Pongamia pinnata (PP), Calophyllum inophyllum (CI), waste cooking oil (WCO), acid oil. Depending their free fatty content, they subjected to the transesterification process produce biodiesel. The main characterizations of density, calorific ...

Waste cooking oil or waste (WCO) is the remaining (or by-products) produced during food frying. In 2019, consumption in Bali Province was 4,735,057 L/month and WCO estimated about 3,314,540 L/month. The Government of plans to manage an integrated manner by processing it as derivative products with economic value. study aimed transform into high-value added (i.e. aromatherapy candles, liquid soa...

Biodiesel is a source of new renewable energies and substitute fuel with much potential in the future for petroleum-derived diesel. According to BP Statistical Review World Energy, total global consumption diesel from petroleum increasing one decade which 3.5 million tonnes 2010 3.9 2019. Despite reducing dependence on fossil fuel, question how waste cooking oil (WCO) disposal related environme...

Cooking oil waste leads to well-known environmental impacts and its bioremediation by lipase-based enzymatic activity can minimize the high cytotoxic potential. In addition, they are among the biocatalysts most commercialized worldwide due to the versatility of reactions and substrates. However, although lipases are able to process cooking oil wastes, the products generated from this process do...

Bitumen’s self-healing capability is critical to the bitumen industry’s sustainable development. This work attempts examine property and fatigue behavior of using waste cooking oil (WCO) polyphosphoric acid (PPA) in modification. Different components WCO were mixed with PPA for initial The linear amplitude sweep (LAS) test was used evaluate modified bitumen. To assess extent healing after a fat...

Biodiesel has gained wide acceptance as an alternative to petroleum-derived fuel due its environmentally friendly characteristics such low aromatic and sulfur content, biodegradability exhaust gas emission. Although many types of feedstock could be used produce biodiesel, waste cooking or frying oil (WCO) is a promising multiple-advantage solution. However, the use WCO biodiesel some drawbacks:...

A potential alternative fuel option is biodiesel, which produced mostly from natural resources due to the limited availability of petroleum supplies and environmental issues. Waste cooking oil (WCO) containing a high concentration free fatty acid (FFA) can be transformed into substantially benefits environment for reducing . The use smectite clay as catalyst in esterification reaction WCO with ...

The present contribution investigates the biocatalytic performance of lipase obtained from latex native plant known as Araujia sericifera (ASL) in hydrolysis followed by esterification released free fatty acids and transesterification glycerides sunflower waste cooking oil WCO. A specific enzymatic activity 719.05 ?mol mg?1 h?1 (60 % conversion triglycerides towards acids) was WCO with 0.05 bio...

The purpose of this study was to investigate the regeneration effect waste cooking oil (WCO) on aged asphalt with molecular dynamics (MD) simulation, comparing it a rejuvenator. Firstly, models virgin and were established by blending four components (saturate, aromatic, resin, asphaltenes). Then, different dosages rejuvenator WCO (6, 9, 12%) included in model for its regeneration. After that, M...
